Fidgets at the Hardware Store

Who knew?  Walking down the home organization aisle at Lowes my gaze was snagged by these Gear Ties:

I'm wearing one of the 12" black ones right now, as a bracelet, to check it out.  If it's durable it will be a great fidget for one of my middle school students.  It does have a rubber coating so it's out of bounds for my students with latex sensitivities.
